Marposs, a measurement, inspection and test technology company, has introduced the e.d.c. AST320/W system to its range of automatic testers for electric motors.
The AST320/W system uses capacitor coupling technology, which is less sensitive to external noise, to assess e.d.c partial discharge for AC High Pot and Surge testing. Electrical motor windings, coils and stators are tested in production situations. The coupling capacitor eliminates the requirement for an external sensor, and utilizing the same wires, the partial discharge measurement test may be done concurrently with the usual AC High Pot and Surge tests without additional testing time.
The AST320’s HMI, which is shared by all e.d.c. testing systems, lets users design tests that include winding resistance, insulation resistance, AC High Pot and surge tests, and communicate with the outside world via digital I/O or OPC UA interfaces. If configured, users can upload data and software to a local area network (LAN) and request remote support. Test and calibration certifications can be printed in several languages and integrated with third-party ERP and MES systems.
